In C#, the def assignment rules are applied to the ctor -- that is,
all fields of the struct must be assigned a value before control
returns from the value type ctor. Thus, we would never have noticed if
the runtime does not 0 init the fields of a struct

+FYI, we never end up noticing this in C# land because we always write:
+
+ IL_0000: ldloca.s 0
+ IL_0002: initobj X
+
+Interestingly, the IL encoding used by nemerle is actually shorter
+than the one mcs uses. Am suprised that this is the case. Today, the
+initobj version is probably much faster speed-wise (it is inlined...)
+however.
